Description

LED down modulated structure

Technical field

The utility model relates to a kind of LED down modulated structure, relates in particular to the good LED down lamp of a kind of radiating effect.

Background technology

Recently since LED have low power consumption, brightness decay slowly, the little advantage such as shock-resistant of long service life, volume, therefore having becomes the trend that replaces conventional bulb gradually; But LED also can produce heat energy, and if the LED of high brightness especially can't efficiently radiates heat, equally also can have influence on the life-span of LED, thus have the dealer develop a kind of shown in patent documentation 1 LED bulb heat radiation structure.

Patent documentation 1: TaiWan, China patent certificate M314505 number " high-capacity LED bulb radiator structure ".

The heat pipe top that the high-capacity LED of above-mentioned patent documentation 1 is arranged with complex cooling fin with bottom surface and is cohered and is had better heat radiating effect, but this heat pipe other end is combined with the lamp holder that generally has the junction surface by a substrate, because heat pipe is made up of complex cooling fin, and fin is a copper foil, be unfavorable for hand grip, especially LED down lamp is installed on the lamp socket or when unloading on the lamp socket, how therefore the capital design a kind of great heat radiation effect of being convenient to grasp and have because there is not the grasping part to make installation or removal produce difficulty, the LED down lamp of taking into account appearance and modeling again just is main purpose of the present utility model.

Summary of the invention

The purpose of this utility model is, by a kind of LED down lamp is provided, makes it to be convenient to grasp and has great heat radiation effect, takes into account appearance and modeling again.

The utility model technological means is achieved in that a kind of LED down lamp, it is characterized in that comprising: one by junction (11) and have the lamp holder (1) that the clamshell (12) of radiating effect is formed; One end is fixedly arranged in the aforementioned clamshell (12) and holds in addition and is exposed to the outer radiating module (2) of clamshell (12); And one be located at radiating module (2) in addition end face and the high-brightness LED (3) that electrically connects with aforementioned lamp holder (1).

According to above-mentioned LED down modulated structure, described clamshell (12) is that flaring metal heat-conducting material is made, and has been peripherally installed with some radiating fins (121).

According to above-mentioned LED down modulated structure, described radiating fin (22) be shaped as circle.

According to above-mentioned LED down modulated structure, described radiating fin (22) be shaped as semicircle.

According to above-mentioned LED down modulated structure, described radiating module (2) by at least one thermal conductance post (21), and multi-disc uniformly-spaced arrange and the radiating fin (22) that is fixed in thermal conductance post (21) that overlaps is formed.

According to above-mentioned LED down modulated structure, described high-brightness LED (3) is a kind of chip type LED.

According to above-mentioned LED down modulated structure, other end face of described radiating module (2) more is provided with a ring and covers in high-brightness LED (3) taper reflector (4) on every side.

According to above-mentioned LED down modulated structure, described reflector (4) is that shell is moulded in a taper, and the splendid plated film layer of one deck light reflectance is established in wall plating within it.

The utility model compared with prior art has following remarkable advantages and beneficial effect:

Radiating module (2) one ends are fixedly arranged in the clamshell (12) that is peripherally installed with radiating fin, have the better radiating effect except increasing area of dissipation, also can make the moulded than the tool characteristic of LED down lamp simultaneously.

Therefore radiating module (2) is fixedly arranged in the clamshell (12), when installation or removal LED down lamp, can be convenient to the hand-held clamshell (12) of operator and is beneficial to group and unloads.

After setting up reflector (4), high-brightness LED light is concentrated, and produced better radiation response.

The specific embodiment

Following according to detailed description of the embodiment shown in the drawing as back:

As shown in Figure 1, be the three-dimensional exploded view of the utility model LED down modulated structure; Fig. 2 is the three-dimensional exploded view at another visual angle of the utility model LED down modulated structure; Fig. 3 is the three-dimensional combination figure of Fig. 1; Fig. 4 sets up the schematic diagram of reflection photograph for Fig. 1; Fig. 5 A～Fig. 5 D is another enforcement view of Fig. 1 lamp holder; Fig. 6 is another enforcement view of the utility model radiating module, and Fig. 7 is another enforcement state schematic perspective view of the utility model radiating module.

By comprising forming of LED down lamp as can be known among the above-mentioned figure: one by junction (11) and have the lamp holder (1) that the clamshell (12) of radiating effect is formed; One is fixedly arranged in the aforementioned clamshell (12) and part is exposed to the outer radiating module (2) of clamshell (12); And the high-brightness LED (3) being located at radiating module (2) end face and electrically connecting with lamp holder (1).
